Is it true that weather phenomena don't necessarily happen in the atmosphere?

Weather phenomena do not necessarily occur in the atmosphere.

This sentence is wrong. Weather phenomena generally occur in the atmosphere, which is divided into five layers, most of which occur in the troposphere.

The atmosphere is divided into troposphere, stratosphere, mesosphere, ionosphere/thermosphere and outer layer. Most climate phenomena occur in the troposphere. The closer the troposphere is to the ground, the higher the temperature, and the farther it is from the ground, the lower the temperature. The air near the ground rises and gradually cools, forming convection, which is an important condition for precipitation.

Characteristics of troposphere:

The troposphere of the earth is the atmosphere closest to the surface of the earth, which concentrates about 75% of the atmospheric mass and more than 90% of the water vapor mass. The troposphere is called troposphere because it is influenced by different landforms such as forests, lakes, grasslands, beaches and mountains. And the temperature change caused by sunlight, which causes vertical and horizontal winds, that is, a large number of convection phenomena occur in the air.

The vertical structure of atmospheric temperature from the earth's surface to the height of about 1 10km has its lower limit connected with the ground, its upper limit height varies with geographical latitude and season, and its height varies with latitude, with the average height at low latitudes being 17~ 18 km and the average height at mid latitudes being/kloc-0 ~.
